Plasma prolylcarboxypeptidase (angiotensinase C) is increased in obesity and diabetes mellitus and related to cardiovascular dysfunction.

Abstract

Prolylcarboxypeptidase (PRCP) (angiotensinase C) has 3 major targets, angiotensin II, prekallikrein, and α-melanocyte stimulating hormone(1-13). The truncation of the latter leads to loss in appetite regulation and obesity in experimental animals. The objectives of this study were to purify PRCP from a native source, establish a sensitive immunoassay for PRCP, and relate plasma PRCP concentrations to signs and symptoms of obesity, diabetes mellitus, and cardiovascular dysfunction.
